Exceptional valve hygiene
Minimize the risk of contamination with the unmatched hygiene of the Alfa Laval Unique SSSV. To safeguard your processes, this small, food-grade single seat valve – like all valves in the Alfa Laval SSV range – has a weld-free body, easy-to-clean plug and double-acting lip seal. Engineered for the dairy, food and beverage and personal care industries, the Unique SSSV is EHEDG-certified, authorized to carry the 3-A symbol and provides full traceability in compliance with the EU Food Regulation 1935/2004.
Cost effective SSSV Valve
Reduce maintenance costs due to the straightforward, hygienic design of the Unique SSSV. Few moving parts and crevice-free surfaces prolong the intervals between Cleaning-in-Place (CIP). A single contact surface between the plug and the seat minimizes the risk of contamination.
